Elastase & Collagenase

Collagenase and elastase are proteolytic enzymes that mediate tissue remodeling by specifically cleaving major components of the extracellular matrix. Collagenase (typically from Clostridium histolyticum or as matrix metalloproteinases, especially MMP-1 in humans) targets collagen fibers, catalyzing their breakdown and facilitating processes like wound healing, cell migration, and tissue dissociation for laboratory procedures[1][3][5][7]. Elastase (from sources such as porcine pancreas or neutrophils) hydrolyzes elastin as well as other matrix proteins, contributing to tissue elasticity and, when unregulated, to pathological destruction in organs such as the lung, skin, or vasculature[1][4][6]. Both enzymes play physiologic roles in normal tissue turnover and cell migration. Dysregulated or excessive activity is implicated in disorders such as emphysema, chronic obstructive pulmonary disease, fibrosis, cancer invasion, and inflammatory tissue injury[1][4][6]. In drug development and cell biology, their combined or individual use is common for tissue dissociation and experimental disease modeling. The specific inhibitors or recombinant preparations of these enzymes can be used as drugs or research reagents, but improper naming as a single target is incorrect; they should be treated as two separate molecular entities[1][3][6].
